Whenever the mans evil eye falls upon me my blood runs cold so I've made up my mind to take the life of the old man.
Situational Irony
Finally, I have rid myself of that evil eye!!!
Dramatic Irony
Who is there?
He says he is not mad/crazy but really is.
He had killed the old man but we thought he wouldn't because he was crazy and we thought he was just saying things.
We knew the crazy man was gonna kill the old man but the old man did not have a clue he was gonna die because he thought the man liked him so he didn't expect anything.
